MDS Trivex Plus 70 & Plus 80

The M DS Trivex Plus 80 System includes the 8074 Remote Controller and the 8078 Display Station. Up to 32 devices can be connected to the 8074, including 8078 displays and MDS Trivex 8087 serial printers (not shown). The Plus 80 components are fully plug-compatible with the IBM 3274 controller and the IBM 3278 display, and feature SNAj SDLC protocol compatibilty.

MANAGEMENT SUMMARY

MDS Trivex, a subsidiary of Mohawk Data Sciences, currently offers two families of plug-compatible replacements for the IBM 3270 Information Display System. The Plus 70 family, introduced in 1975, consists of controllers offering 3271/3272 compatibility, and displays offering 3275/3277 compatibility. The Plus 80 family was unveiled in late 1979 with the introduction of a 3278-compatible display. In June 1980, MDS Trivex expanded the Plus 80 family by adding a 3274-compatible controller.

A major advantage of the MDS Trivex Plus 70 and Plus 80 systems is that they are fully interchangeable with exist- ing IBM 3270 components; i.e., IBM display stations and printers can be attached to MDS Trivex controllers and the converse. The Plus 70 and Plus 80 are also designed to use existing IBM cables, although MDS Trivex does' furnish its own.

The MDS Trivex Plus 70 and Plus 80 provide complete compatibility with the IBM 3270 with respect to line 1>

Plug-compatible replacements for first and second generation members of the IBM 3270 Information Display System.

Plus 70 components include: remote and local controllers compatible with the IBM 3271 and 3272; a 3275-compatible stand- alone display station; a cluster display compatible with the 3277; and a mini-cluster display. Components of the newer Plus 80 series include a 3274-compatible controller and a 3278-compatible display. Impact printers are available for both the Plus 70 and Plus 80 families.

A typical Plus 80 configuration including a remote controller, 16 displays, and two printers is priced at $1.841 per month on a two-year lease.

The MDS Trivex terminals also provide all the features and functions that are currently available with the specific IBM 3270 components they emulate, as well as some worthwhile enhancements, such as easier-to-use self -diagnostics, a Wider range of trans- mission rates, and switchable screen capacities. . MDS Trivex has implemented SNA/SDLC protocol compatibility on the Plus 80 Series. The older Plus 70 Series, however, does not support SDLe.

The Series 800 Printer Stations are available for use with the Plus 70 Series. Two models of serial impact printers are available, as buffered or unbuffered units; both feature print speeds of 165 cps. In November 1981, MDS Trivex enhanced the Plus 80 Series with the addition of the Model 8087 Printer. The 8087, a plug-compatible replacement for the IBM 3287, is an impact printer with a print speed of 180 cps.

Trivex, Inc. was an early manufacturer of replacement CRT terminals for the IBM 2260 and 2265 market. The company entered the IBM 3270 replacement market in 1975 with the introduction of the Plus 70 Series. Trivex was acquired by Mohawk Data Sciences Corporation in January 1979, and the company's name was changed to MDS Trivex.

USER REACTION

In Datapro's 1981 survey of alphanumeric display terminal users, four responses were received from users of MDS Trivex equipment. All four users responding reported on their experiences with Model 8078 (Plus 80) Display Stations. A total of 70 displays were installed at the four user sites. The ratings given for the MDS Trivex terminals are summarized in the following table.

~ four adapters for 32 devices. Models 0712 and 0722 are interchangeable with IBM's Model 3271-2 and 3272-2 Control Units, respectively.

The Model 0712M mini-cluster controller includes a master display station and contains one device adapter that can ' accommodate up to four devices, including the master display station. Four additional devices can be accommodated via one additional device adapter (Display Expander).

Master display station characteristics are identical to those of the Model 0772 Display Station, except that the master display station will not support the optional OCR Wand.

There are no option restrictions for the seven additional devices attached to the 0712M controller. Model 0712M is interchangeable with the IBM 3276-2 Control Unit/Display Statim.

In each of the cluster configuratims, including the mini- cluster, the control unit provides individual buffering for each device, which can be located up to 2000 cable-feet from the control unit. Each display unit can support a light pen and an OCR hand-held wand.

The Model 0772 Display Station and 0800 Series printers are interchangeable with IBM 3270 equipment and can be directly connected to IBM controllers in place of the equivalent IBM components.

The Plus 80 Series currently includes the Model 8078, a cluster terminal replacement for the IBM 3278, and the Model 8074 Controller, a plug-replacement for the IBM 3274 Control Unit. MDS Trivex has also added the 8087 printer, a plug-replacement for the IBM 3287 printer.

In the basic Plus 80 configuration, the 8074 Remote Controller can accommodate up to 32 Category A devices, including the 8078 Display Models 1, 2, 3, or 4, the 8087 Printer, or the equivalent IBM components. The 8074 provides control for up to 24 Category B devices, including the 0772 Display, the Series 800 Printers, or the equivalent IBM components. The basic controller contains a device adapter that will control up to eight devices. The unit can be expanded to 32 devices by additional device adapters to increment the devices by eight.

TRANSMISSION SPECIFICATIONS

Transmission is half-duplex, synchronous at switch-selectable data rates from 300 to 9600 bits/second using 8-level EBCDIC transmission code. The remote controllers provide an EIA Standard RS-232C interface for connection to a voice-grade communications facility via a modem. Bell System modems that can be used include the 103A/F or 113A/B (up to 300 bps) and the Dataphone 1200, 1800, 2400, 4800 and 9600.

DEVICE CONTROL

The MDS Trivex Plus 70 and Plus 80 operate under the control of the program stored at the computer and provides complete compatibility with the addressing sequence, command code structure, and line discipline employed by the IBM 3270 Information Display System. The Plus 70 and Plus 80 respond to and execute the full repertoire of IBM 3270 commands via a firmware-controlled microprocessor.

Cursor control is functionally the same as in the IBM 3270.

The controls position the cursor up, down, left, or right, either step-by-step or repetitively (if the key is held down);

the cursor can also be backspaced one character position, moved to the beginning of tbe next line or the next unprotected data field, tabbed to the beginning of the next unprotected data field, backtabbed to the beginning of the previous unprotected data field or home position, and reset to line position. Switch selection provides cursor blinking or

nonblinking. ~

~ Program Function and Program Attention keys, a standard feature of the IBM 3270, are also standard in the Plus 70 and Plus 80. Each of these keys generates a unique code that is recognized by the controUing software as a specific program request or data identifier. Program Function codes accom- pany the display data as it is transmitted to the computer, while Program Attention codes are transmitted separately.

A light pen is available as an option for the clustered displays and functionally corresponds to IBM's Selector Pen, a 3270 option. Anyone or several alphanumeric or numeric fields of fixed or variable formats can be selected by the pen, which transmits the address of the selected entry to the computer to initiate the programmed function.

Structured data entry, a la displayable formats, is supported via attribute codes, which define protected fields, delimit data entry fields, and specify display parameters and tab stop positions. The use of attribute codes is the same as for the IBM 3270. Optionally, each character position in a data entry field can be IDled with dots, which are replaced by keyed data. Character and field blanking can be specified by the program, which can also specify high or low beam intensity.

Edit controls are the same as those for the IBM 3270 and include character insertion and deletion within a field. screen (and memory) erasure, field erasure, partial field erasure (specified by the cursor position), and duplication of data specified by a unique code, which is displayed as an asterisk.

The switch-selectable audible alarm alerts the operator upon Ilega! entry.

The Display Print option provides a local copy capability, without intervention from the host. Two local print modes are provided. Priority Print produces a printed copy of the entire contents of the display buffer by the fll'St available printer. Assigned Print prints the contents of a display buffer on a printer assigned by the display station operator.

In addition to the IBM standard on-line indicators, the Plus 70 provides five terminal status indicators. A diagnostic program is also provided for off-line self test and fault isolation in each system component.

The MOS Trivex Plus 70 and Plus 80 provide complete compatibility with the IBM 3270 with respect to line discipline, commands and command-code structure, and addressing sequence. The MOS Trivex terminals also provide all the features and functions that are currently available with the specific IBM 3270 components they emulate, as well as some worthwhile enhancements, such as easier-to-use self-diagnostics, a wider range of trans- mission rates, and switchable screen capacities. Trans- mission speeds for the Plus 70 and Plus 80 range from 300 to 9600 bits per second, compared with 1200 to 7200 bits per second for the IBM 3270. However, support for SOLe protocol is not provided by MOS Trivex.

MOS Trivex currently offers two models of serial impact printers rated at 165 cps or 125 Ipm. The printers offered by MOS Trivex have 132 print positions and a 1920- character buffer so that (in cluster configurations) print- ing does not affect system throughput speed. By com- parison, IBM offers impact printers rated at 40, 66, or

120 cps and line printers rated at 120 or 300 lpm. All are available with 132 print positions and are buffered.

MDS Trivex, an early manufacturer of replacement CRT terminals for the IBM 2260 and 2265 market, introduced itself to the IBM 3270 environment in May 1975 as a manufacturer and vendor of IBM 3270-compatible terminals.

USER REACTION

In Oatapro's 1979 survey of alphanumeric display ter- minal users, responses were received from eight MDS Trivex Plus 70 users reporting on their experiences with a total of 17 units. Their ratings are summarized below.

*Weighted Average on a scale of 4.0 for Excellent.

All eight users reported that they were using the display as a plug-compatible replacement for the IBM 3270/3275.

They were divided evenly with respect to configuration:

four used their Plus 70's as single stations and four as clustered stations.

A high degree of user satisfaction with the MDS Trivex Plus 70 is indicated by the ratings for every aspect except Technical Support. The physical size of the unit was cited as an advantage by four users. Interestingly, four respon- dents cited price as a strength while four others listed it as a weakness.D

~ OCR wand and a light pen can also be added. Model 0752 is interchangeable with an IBM 3275 Model 2 operating in half- duplex mUltipoint mode on full duplex facilities at speeds up to 9600 bps.

The Model 0712 remote cluster controller and Model 0722 local cluster controller can each accommodate up to 32 devices including any combination of Model 0722 display stations and 165-cps or 125-lpm printers. The basic controllers contain a device adapter that can accommodate up to eight devices. Eight additional devices can be accommodated via each subsequent device adapter, up to a total of four adapters for 32 devices. Models 0712 and 0722 are interchangeable with IBM's Model 3271-2 and 3272-2 Control Units, respectively.

The Model 0712M mini-cluster controller includes a master display station and contains one device adapter that can accommodate up to four devices, including the master display station. Four additional devices can be accommodated via one additional device adapter (Display Expander).

Master display station characteristics are identical to those of the Model 0772 Display Station, except that the master display station will not support the optional OCR Wand.

There are no option restrictions for the seven additional devices attached to the 0712M controller. Model 0712M is interchangeable with the IBM 3276-2 Control Unit/Display Station.

In each of the cluster configurations, including the mini- cluster, the control unit provides individual buffering for each device, which can be located up to 2000 cable-feet from the control unit. Each display unit can support a light pen and an OCR hand-held wand.

Models 0712 and 0712M, the remote controllers, support BSC protocol and are attached to a communications facility via a modem. The maximum cable length between controller and modem is 50 feet. Model 0722, the local controller, contains a channel interface for direct connection (via up to 200 cable-feet) to an IBM System 360 Models 25 through 195 or IBM System/370 Models 115 through 195, via a Selector, Multiplexor, or Block Multiplexor Channel. The data transfer rate can range from 10K to 650K characters per second.

The Model 0772 Display Station and 0800 Series printers are interchangeable with IBM 3270 equipment and can be directly connected to IBM controllers in place of the equivalent IBM components.

The Plus 80 Series currently includes only the Model 8078, a cluster terminal replacement for the IBM 3278. Announce- ment of a Model 8074 Controller is anticipated for May 1980; the new controller is expected to be a plug-replacement for the IBM 3274 Control Unit.

TRANSMISSION SPECIFICATIONS

Transmission is half-duplex, synchronous at switch-selectable data rates from 300 to 9600 bits/second using 8-level EBCDIC transmission code. The remote controllers provide an EIA Standard RS-232C interface for connection to a voice-grade communications facility via a modem. Bell System modems that can be used include the 103A/F or 1I3A/B (up to 300 bps) and the Dataphone 1200, 1800, 2400, 4800 and 9600.

DEVICE CONTROL

The MDS Trivex Plus 70 and Plus 80 operate under the control of the program stored at the computer and provides complete compatibility with the addressing sequence, command code structure, and line discipline employed by the IBM 3270 Information Display System.

MDS Trivex Plus 70 & Plus 80

~ Plus 80 respond to and execute the full repertoire of IBM 3270 commands via a firmware-controlled microprocessor.

Cursor control is functionally the same as in the IBM 3270.

The controls position the cursor up, down, left, or right, either step-by-step or repetitively (if the key is held down);

the cursor can also be backspaced one character position, moved to the beginning of the next line or the next unprotected data field, tabbed to the beginning of the next unprotected data field, backtabbed to the beginning of the previous unprotected data field or home position, and reset to line position. Switch selection provides cursor blinking or non blinking.

Program Function and Program Attention keys, a standard feature of the IBM 3270, are also standard in the Plus 70 and Plus 80. Each of these keys generates a unique code that is recognized by the controlling software as a specific program request or data identifier. Program Function codes accom- pany tbe display data as it is transmitted to the computer, while Program Attention codes are transmitted separately.

A light pen is available as an option for the clustered displays and functionally corresponds to IBM's Selector Pen, a 3270 option. Anyone or several alphanumeric or numeric fields of fixed or variable formats can be selected by the pen, which transmits the address of the selected entry to the computer to initiate the programmed function.

Structured data entry, a la displayable formats, is supported via attribute codes, which define protected fields, delimit data entry fields, and specify display parameters and tab stop positions. The use of attribute codes is the same as for the IBM 3270. Optionally, each character position in a data entry field can be filled with dots, which are replaced by keyed data. Character and field blanking can he specified by the program, which can also specify high or low beam intensity.

Edit controls are the same as those for the IBM 3270 and include character insertion and deletion within a field, screen (and memory) erasure, field erasure, partial field erastire (specified by the cursor position), and duplication of data specified by a unique code, which is displayed as an asterisk.

The switch-selectable audible alarm alerts the operator upon illegal entry.

The Display Print option provides a local copy capability, without intervention from the host. Two local print modes are provided. Priority Print produces a printed copy of the entire contents of the display buffer by the first available printer. Assigned Print prints the contents of a display buffer on a printer assigned by the display station operator.

In addition to the IBM standard on-line indicators, the Plus 70 provides five terminal status indicators. A diagnostic program is also provided for off-line self test and fault isolation in each system component. .

COMPONENTS

MODEL 0772 (PLUS 70) DISPLAY STATION: A CRT display unit with 15-inch (diagonal measurement), anti-glare screen and detachable keyboard. The display area measures 8 inches high by tt inches wide. The display arrangement is 24 lines of 80 characters each for a total of 1920 characters.

An optional 25th line, displayed above the first line in the right-hand sector, is used for operator prompting (displayed messages) and line and character position counts. A character set of 64 or 96 (optional) EBCDIC symbols including upper and lower (optional) case alphabetics, numerics, and special symbols is displayed in white or green (optional) against a dark background. Each character is formed by a matrix of 7 by 9 dots to allow for lower case descenders. Dots

are displayed in variable field locations. A blinking or nonblinking cursor is switchable. The display unit contains a 768 word PROM memory expandable to 4K for control program (fu-mware) storage and a 2K RAM display memory expandable to 4K.

The display station is interchangeable with the IBM 3277 Model 2 and can be attached directly to an IBM controller in place of the IBM display station.

MODEL 8078 (PLUS 80) DISPLAY STATION: A CRT display unit with a 15-inch (diagonal measurement) screen and detachable keyboard. Four versions are available which differ only in their display capacities: Model 8078-1 can display 480 or 960 characters (12 lines of 40 or 80 characters);

Model 8078-2 displays 1920 characters (24 lines of 80 characters); Model 8078-3 can display 1920 or 2560 characters, (24 or 32 lines of 80 characters); and Model 4 can display 1920 or 3440 characters (24 or 43 lines of 80 characters).

Below the last data display line is an operator information area that displays operator, status and error messages. A 94- character set, including upper and lower case alphabetics, in either EBCDIC or ASCII code is provided as standard. Each character is formed by a 7-by-14 dot matrix (Models I, 2, and 3) or 7-by-9 dot matrix (Model 4). A blinking or nonblinking block or underline cursor is switch-selectable. A monocase switch provides an upper-case-only mode compatible with MDS Trivex 0772 or IBM 3277 displays.

The display station is interchangeable with the IBM 3278 Di<iplay Station and can be attached directly to an IBM Model 3276 or 3274 controller in place of an IBM display station.

Five detachable keyboard models including typewriter, data entry, and operator console keyboard styles are available.

All models generate the EBCDIC code exclusively. Three models of typewriter-style keyboards include a 66-key (Model 0630) version, a 78-key (Model 0633) version (with 12 Pro- gram Function keys), and a 78-key (Model 0634) version with combined 12-key numeric pad and Program Function keys. The Program Function keys are enabled via shifting.

The two other keyboards include a 66-key data entry style keyboard and a 78-key operator console keyboard. Keyboard options include N-Key rollover and a security keylock.

Six keyboards including typewriter or data entry styles, are available. The four typewriter-style keyboards feature com- binations of EBCDIC or ASCII character sets with or without a 12-key numeric/Program Function cluster (the 12 Program Function Keys are enabled by shifting). The two data entry keyboards provide EBCDIC character sets only;

one of the two versions is a data entry/keypunch keyboard that provides standard keypunch placement of the Enter key.

Alphanumeric, special symbol, and cursor movement keys are typamatic and are set at a standard speed of 10 cps.

Optionally, the cursor movement, tab and backtab, and new Hne keys can be set at 20 cps, and the space bar and dash (underscore) keys at 30 cps. A security lock is also optional.

LINE PRINTER: Models 0884 and 0883 are shuttle matrix printers with 132 character positions and are rated at 125 lines/minute. Modei 0884 is a microprocessor-controlled buffered printer interchangeable with the IBM 3288 printer for use on Trivex or IBM controllers. Model 0883 is unbuffered and is designed for use with the Trivex 0752 Stand Alone Display Station. The standard character set includes 64 upper case symbols; 96- and 128-character symbol sets are optional. Each character is formed within a 5-by-7 or 5-by-9 (lower case) dot matrix. Horizontal spacing is 10 characters/

inch; vertical spacing is switchable at 6 or 8 lines/inch. The adjustable tractor feed accommodates multipart forms up to 5 copies (including an original) from 5 to 16 inches wide. An electronic 12-channel vertical forms unit is standard. Rear or
